We study the impact of a minimal length on physical observables for a
three-dimensional axionic electrodynamics. Our calculation is done within the
framework of the gauge-invariant, but path-dependent, variables formalism which
is alternative to the Wilson loop approach. Our result shows that the
interaction energy contains a regularised Bessel function and a linear
confining potential. This calculation involves no theta expansion at all. Once
again, the present analysis displays the key role played by the new quantum of
length.
